Hi, I'm trying to plot some real-time data recieved from an Arduino Uno R3 in matlab R2020b but I'm not sure what baudrate should I set for data transfer. In my case the higher the baudrate is better but if I cant graph it properly it would be of no value. I want to know if I set the baudrate to max (which is 2000000) and since every sample I recieve from arduino would be 10 bits long (it's a number between 0 to 1.1) will I be able to plot them in real time efficiently? is Matlab able to do that?

I think you are asking about a direct connection to MATLAB from an Uno, but most of the workflows here on the ThingSpeak community are about wirelessly connected IoT devices. signal_processing plotting real-time serial sesrial_data
